Ball lightning produced in lab?
Click For Summary
Researchers in Israel have successfully created ball lightning in a laboratory setting, a phenomenon that has intrigued scientists for centuries. This artificial production of ball lightning could enhance our understanding of its nature and behavior. The reproducibility of this phenomenon is crucial for further research and potential practical applications. The findings are documented in the journal Physical Review Letters. This breakthrough may pave the way for new insights into ball lightning and its uses.
Hello community,
I'm designing a projection lens system for a 35mm film projector in Zemax OpticStudio and struggling with the correct sequential mode setup for the illumination geometry. The light source is a Xenon short-arc lamp reflected by an ellipsoid mirror, which creates a converging cone with a 40.6 degree full angle that passes through the film gate. The film gate is my object plane, but the light doesn't diverge from it like a typical Lambertian source. Instead, the converging...
Hello togehter,
I am new to this forum and hope this post followed all the guidelines here (I tried to summarized my issue as clean as possible, two pictures are attached). I would appreciate every help:
I am doing research on a Particle Image Velocimetry (PIV) system. For this I want to set a simple math model for the system. I hope you can help me out. Regarding this I have 2 main Questions.
1. I am trying to find a math model which is describing what is happening in a simple Particle...
